FRANK O. DEG-ENHARDT, OF NEW YORK, N. Y.

CAROUSEL.

Specification of Letters Patent.

Patented May 2, 1911.

Application filed September 8, 1910. Serial No. 581,006.

To all whom it may concern:

Beit known that I, FRANK O. DEGENHARDT, a citizen of the United Statesof America, residing in the borough of Brooklyn, county of Kings, cityand State of New York, have invented an Improvement in Carousels, ofwhich the following is a specification.

My present invention relates to a carousel and is an improvement on thestructure shown and described in Letters Patent No. 797,347, granted tome August 15, 1905, for an improvement in similar apparatus.

In carrying out my present invention, I

- have dispensed with the lower platform employed in the apparatus asillustrated in the aforesaid patent and have improved the manner ofactuating the swinging bars on or to which the passenger carriages aresecured, so that to these members in my pres cut and improvedconstruction, there is imparted a rocking movement, the shafts to whichthe animal forms or other devices in or upon which the passengers arecarried, being connected to the single revoluble platform in the presentcase in such a manner that this rocking movement is imparted thereto andto the passenger carrying devices. In this construction, the slidingplates employed to cover the upper platform as shown in the patent towhich reference has been made, are entirely dispensed with and theapparatus is otherwise simplified, as will be hereinafter moreparticularly described.

In the drawing, Figure 1 is a central vertical section illustrating thecarousel apparatus comprising my present invention. Fig. 2 is asectional plan on line a", m, Fig. .1, a portion of the platform beingbroken away to illustrate the operating mechanism more clearly. Fig. 3is a sectional elevation illustrating the operating parts in a differentposition to that shown in Fig. 1, Fig. 4 is a plan view of another formof the operating parts, showing the same in a different position thanthey are illustrated in Fig. 1, and Fig. 5 is a partial sectionalelevation showing the manner of supporting the platform.

Referring to the drawing, 10 designates a foundation which may be of anysuitable character and upon which is secured a base 11 which ispreferably double U-shaped in cross section. Secured in the base 11 bymeans of the set screw 13 or otherwise and extending upwardly from thesame, is a spindle 12, and above the base 11 I employ a cylinder 14. Thecylinder 14 at its respective ends is provided with flanges 1516 and inits under side there is a circular groove 17. I11 the upper surface ofthe outer annular member of the base 11 there is also a circular groove18 of the same diameter as the circular groove 17, these circulargrooves forming raceways to receive the balls 19, so that the cylinder14 is mounted on the base 11 upon a ball bearing. On the under side ofthe cylinder 14 there is a bevel gear 20 adapted to mesh with a bevelgear 21 secured on the end of a drive shaft 22 which is journaled in asuitable bearing 23 fixed on the foundation 10, and as will beunderstood, the drive shaft 22 may be driven from any suitable source ofpower.

Mounted on the spindle 12 above the cylinder 14 I employ a head memberindicated at 24 and this is secured or fixed in position on the spindle12 by means of a set screw 25 or otherwise and on the under face of thehead 24 a spur gear 26 is secured. The head 24, the gear attachedthereto, the spindle 12 and the base 11 are fixed on the foundation 10.

In equally spaced apart positions in the flanges 15 and 16 of thecylinder 14, shafts indicated at 27 are journaled. Each shaft 27 abovethe flange 15 is provided with a gear 28 adapted to mesh with the gear26.

Each shaft 27 is also provided with a crank disk 29 above its gear 28and in each crank disk 29 a pin 30 is secured and each pin 30 carries acollar indicated at 31.

32 designates a platform which may be made of any suitable material andso c011- structed as to be secured to the cylinder 14 by means ofbrackets 33 which are connected at one end to the under side of theplatform and at the opposite end to the flange 15 of the cylinder 14 asshown in Fig. 5, the central portion of the platform 32 being open andadapted to pass over a reduced upper end of the head 24 and to rest upona shoulder 34 provided in the head 24 by reason of the reduced upper endthereof.

35 designates a passenger carriage which comprises a car having doors oropenings at the opposite ends thereof and seats running longitudinallythe entire length of the car, whereas 36 designates the form of ananimal which in accordance with my present invention I may also employas a carriage upon which passengers may ride. The car 35 is connected toa shaft 37, the upper end of which is secured to a flange 39 fixedcentrally to the under surface of the floor of the car, the shaft 37passing through a sleeve 38 fixed in the platform 32 and also throughthe platform 32 and extending an appreciable distance below the same.

At its lower end the shaft 37 is provided with a crank arm 40 connectedthereto in any suitable manner, and at its outer or free end the crankarm 40 carries a pin 41 over which is fitted a collar 42. This collar42, on the opposite sides thereof, is provided with projecting trunnions44, by means of which the bifurcated end of the connecting rod 43 ispivotally connected. The opposite and similarly bifurcated end of thisconnecting rod 43 is pivotally connected to trunnions 45 extending fromopposite sides of one of the collars 31 on one of the pins 30.

By this construction as will be apparent from Figs. 1 and 4, theplatform is revolved from the drive shaft 22 which turns the cylinder14, and that by means of turning these parts, the gear 28 will turn thecrank disks 29 and the same will actuate the connecting rods 43, wherebythrough the crank arm 40 a rocking movement will be imparted to theshaft 37 which in turn imparts this rocking movement to the carriage 35,so that together with being carried around by the platform 42, thecarriage 35 is also given a rocking or oscillating or partial rotarymotion.

Referring to the left hand portion of Fig. 1 and to Fig. 3, it will beunderstood that I may also employ a series of shafts 46 upon the upperend of which an animal 36 or other device is mounted. Each of theseshafts 46 passes through the platform 32 and is provided with a collar48 having pins 49, by means of which the shaft 46 is pivotally connectedbetween the upper surface of the platform 32 and a strap secured theretoand employed for this purpose. Beneath the platform 32, each shaft 46 isfitted with a collar 50 also provided with trunnions 52 extend ing fromopposite sides thereof, to which trunnions the bifurcated end of theconnecting rod 51 is pivotally connected, the oppositely and similarlybifurcated end of this connecting rod 51 being connected to thetrunnions 45 extending from opposite sides of one of the collars 31, sothat as the cylinder 14 and the platform 32 are revolved by turning thedrive shaft 22, the reciprocating movement imparted to the connectingrod 51 is transmitted to the shafts 46 to impart a rocking movementthereto.

Connected to the platform 32 I may employ a. suitable frame comprising aseries of uprights 54 secured at their lower ends to the platform 32 andattheir upper ends to a ring 55.

The upper end of the spindle is preferably of reduced cross section toreceive the sleeve 56 which performs the function of the kingpost, thetie-beams 57 extending therefrom to the ring and the rafters or inclinedmembers 58 also extending from the sleeve 56 at the upper end thereof tothe said ring 55.

Above the head 24 I may also employ a fixed platform indicated at 59secured thereto by screws 60 or otherwise. I may also employ anauxiliary drive-shaft 61 journaled in any suitable manner and fittedwith a bevel gear 62 meshing with a similar gear 63 secured on avertical shaft 64 which at its opposite end carries a spur gear 65meshing with a gear 66 secured to the upper surface of the platform 32,so that if it is desired or if itis more convenient, the revoluble partsof the carousel may be operated from a motor or other driving mechanismsituated above the platform and the drive shaft 22 below the platformentirely dispensed with.
